Revopoint Mini Turntable Speed Knob

I find it extremely difficult to control the speed of the Revopoint Mini Turntable T-125 during use. Especially when using a marker topper plate.

To solve this, I designed a small knob that improves grip, making it easier to adjust the turntable speed while using it.

I've also designed a marker topper plate for the Mini Turntable T-125, check it out.
